phalcon框架中怎么实现脱离模型进行sql查询

分享到：
------解决方案--------------------
$ar = $obj->fetchAll($sql);
或
$r = $obj->fetchOne($sql);

其实 Phalcon 的类都是可以单独使用的，并不一定非要在框架中使用
比如

$connection = new \Phalcon\Db\Adapter\Pdo\Mysql(array(
        "host" => "localhost",
        "username" => "root",
        "password" => "",
        "dbname" => "test"
    ));
//print_r(get_class_methods($connection)); //从支持的方法上看，只不过是在PDO上扩展了一些功能
$connection->query('set names gbk');
$t = $connection->fetchAll('select * from `123`', 1);
print_r($t);
